        <p id="shortdesc">
            This example shows how to reproject vector features within 
            OpenLayers. The baselayer shows Germany in the projection 
            EPSG:31467 (GK 3). When one clicks on the buttons, features with
            geometries originally in EPSG:4326 will be transformed to the 
            projection of the map on-the-fly.
        </p>
        <p>
            The features are internally reprojected with the JavaScript library 
            <a href="http://proj4js.org/">Proj4JS</a>. Please note that usually
            you would not inlude Proj4JS the way it is done in this example.
            In a production environment you would furthermore have a local copy 
            of the Proj4JS-projection definition that is hotlinked in this 
            example (see Graticule example for how to do this).
